This mod unlocks Roboports and Logistic chests from the start of the game so that you can use them very early. No advanced circuits required. Items are transported between logistic chests instantly and without the need for logistic robots, so throughput can be scaled as much as needed.
Roboports do not need power. They are required to enable logistic chests, however. This is to make long-distance item transportation with logistic chests more balanced. To stop Roboports from flashing the out-of-power signal, connect a power pole to them.
This mod is extremely useful for large mods/modpacks like Bob's, Angel's, Pyanodon's, and Yuoki's mods, where you'll be working with a very large variety of complex materials. The complexity of such mods inspired the creation of this mod.
Realistically speaking, logistic chests are like freight trucks. They transport goods from one manufacturing center to another. This allows for complex production webs without the need for conveyors to be placed everywhere. The same concept can be replicated in factorio with this mod.
